ABC on the fritz

Just had the front driver strut replaced. All seemed well. Until just now, car was idling for about 30 min and when I drove off I got the dreaded abc malfunction vehicle too low message. Looked outside and all 4 sides dropped!

Then I put it in park and revved the engine a bit and the car rose to regular ride height. What gives?! Signs that my pump is failing? Valve block?

I would guess the ABC pump is giving out.

Agree, most likely pump failure. You'll need to get it replaced as soon as you can.

Do you hear any ticking noise in front of the engine? Could also be some random quirk.
